The figure above displays a three-dimensional bar chart of the percentage of men
with high HDL-cholesterol (60 mg/dL or higher, the level considered
sufficiently protective as to eliminate the detrimental effects of one
other CHD risk factor). The height of the bars represent the percent of men.
When viewed from left to right, the graph shows that the percentages
increase linearly with incremental increases in running distance regardless
of alcohol intake. When viewed from front to back, the graph shows that
the percentages increase linearly with incremental increases in alcohol
intake regardless of distance run. Men who ran over 45 miles and drank
over 6 oz. of alcohol per week (between one and a half and two beers
or glasses of wine per day) were five times more likely to have high
HDL as nondrinkers running less than 15 miles per week.
